Manteufel, the tires themselves are really impressive in terms of grip offered. Ive ridden on frozen hard pack, light packed snow and some ice and they offer great traction. They roll pretty well when ridding pavenent to and from the trail. They do however have very weak sidewall puncture resistance. I caught a tiny stump with my front tire and it did cut the sidewall requiring me to patch it from the inside as the gash was too big for sealant to take care of. This may just be a function of really soft tire compound so that it can still operate sub 0 and weak sidewall reinforcement to save on weight. Also you have way more sidewall exposed on a fat tire bike so likelihood of catching something is greater. Overall I'm pretty happy with but haven't had the opportunity to try them in fresh deep snow so jury is still out.
My LBS owner didn't recommend studding these as he has a pair of them studded and says that he loses around ten percent of studs on each ride.... Pass

Try studding them with some locktite. Be extra-sure you got the stud seated properly in the pocket (so spend a little extra time). After a week or so of rides, I stopped losing studs.

That said, still get a few more than the tire takes for this reason.
